Porites are small polyp stony (SPS) corals in the Poritidae family. These corals mostly grow by encrusting and can grow into mounds. When the polyps are extended, Porites appear fuzzy. These corals are usually found in shades of yellow, green, pink, and tan. However, there are other color morphs found in aquaculturing. Porites are commonly called, “Yellow finger coral” or “Jeweled finger coral.”
Porites corals require moderate to high lighting. We recommend around 200-350 PAR depending on the particular species of Porites. Bear in mind that most corals can be gradually adapted to lighting conditions outside of their normal preferences. Porites also prefer strong water flow.
One of the best things about Porites corals are "Christmas Tree Worm" rocks. This is when a big piece of Porites is colonized by a variety of colorful tube worms with spiraling crowns shaped like a Christmas tree, hence the name. When disturbed or startled, these little worms will retreat quickly into their hidden tubes. Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, Porites receive many of their nutrients. To maintain good health, calcium, strontium, and other trace elements should be monitored and added as needed.
Porites have short tentacles and are pretty peaceful corals. Be sure to provide a plenty of space for your Porites corals to grow and thrive. Porites colonies can grow large and make up some of the largest colonies in the ocean reefs.
